LOCK-HINGE.

SPECIFICATION forming part of Letters Patent No. 283,128, dated August14, 1883.

Application filed January 9, 1853. (No model.)

To all whom, 1119 may concern.

Be it known that I EGBERT E. MAs E s, of Woodland, county of Yolo, Stateof California, have invented an Improved Hinge; and I hereby declare thefollowing to be a full, clear, and exact description thereof.

My invention relates to a new and useful lock-hinge; and itconsists incertain improve ments in the pawl and-ratchet mechanism by which itoperates, as I shall hereinafter explain, reference being made to theaccompanying drawings, in which Figure 1 is a perspective view of myhinge.

Fig. 2 is a horizontal section, showing its ap hinge and keep the doorshut completely, or

plication to frame and door.

The object of my invention is to provide a useful hinge for screen andinside doors, window-blinds, gates, &c., which require to beheld opentemporanily.

A is a portion of a'door-fra me, and B a part of a screen-door.

O 0 are the plates of the hinge, screwed to the frame and door. .Uponthese plates are flanges or projections forming bearings 0 c,in whichthe pintle or shaft D is fitted. ings a of plate 0 have their facesformed into ratchets, as shown. Upon the bearings c are formed guides 6,under which aplate, F,is fitted, and is adapted to be moved forward toengage with the ratchetbearings c, orto be withdrawn to free them. Whenengaged therewith, the hinge is locked in whatever position it happensto be. When the plates 0 O are in line, the locking plate or pawl F maybe moved forward to engage with the under or last tooth of the bearings,and thus lock the hinge works freely.

The bear it may engage with any of the teeth, and thus hold the doorajar. When drawn back, the In, the plate F is made an elongated slot, f,in which an eccentric, g, on a shaft, h, is adapted to operate. Theshaft h extends through the door, and is bent to form a handle. -Byturning this it moves the plate F into or out of engagement with theratchet-bearings. i

E is a spring on the pintle D, and operating to close the door when theplate F is re leased. s

I am aware that ratchet-bearings operating similarly to mine have beenheretofore used; but their ratchets and the means for operating the pawlmechanism are not constructed like mine, which are easy of separation. II do not claim, broadly, aratchet-hinge, but simply theconstruction Ihave shown and described. Having thus described my invention, what Iclaim. as new, and desire to secure by Letters Patent, is-

In a hinge, the plate 0, having ratchet-bearings c, the plate C, havingbearings c and guides e, and the pintle or shaft D, passing throughbearings c c, in combination with the locking-plate F on plate C,sliding ;in the guides e, and having slot f, the shaft h, and

eccentric 9, all arranged and operating sub' stantially as hereindescribed.

In witness whereof I hereunto set my hand.
